fix: replace blocked preview sticky comment action (#3113)

The `actions-cool/maintain-one-comment@v3` repository was blocked by
GitHub for a Terms of Service violation on 2026-05-19, causing all
"Preview sticky comment" workflow runs to fail.

Replace with `marocchino/sticky-pull-request-comment@v2`, which
provides the same sticky comment functionality.
